HEAVY METAL QUANTIFICATION WITH ICP-OES

QcTestLab Images

Inductively coupled plasma-optical emission spectroscopy (ICP-OES), is a technique used to quantify the concentration of metallic elements in either solid or liquid samples.

With the combination of a special setup of our Perkin Elmer Optima 2000DV ICP OES and a unique methodology we are able to reach detection limits as low as ppb (parts per billion) in many matrices.

We specialize in USP’s “THE BIG 4”: The Four Elements of Primary Concern.

Upon customer request and according to availability of standards, we can also perform quantification of many other elemental contaminants such as Nickel (Ni), Copper (Cu), Chromium (Cr), Cobalt (Co), Molybdenum (Mo), Osmium (Os), Iridium (Ir), Rhodium (Rh), and more.

ICP-OES uses the optical emission principles of exited atoms to determine the elemental concentration.

Liquid samples are nebulized into an aerosol and introduced into the center of an argon induced high-temperature plasma that excites the sample atoms, which subsequently relax to a lower energy state by emitting light at elementally characteristic wavelengths. The intensities of these wavelengths are then detected, and measured by the machine that provides quantitative results.
